Integrating the feedback you hear from the people you’re designing for is one of the essential elements of human-centered design. You learned from people in the Inspiration Phase, and in the Ideation Phase one of the best ways to keep learning from them is to show them what you’ve made and find out what they think. Integrating their feedback into your work and then coming up with another prototype is the best way to refine your idea until it’s something that’s bound to be adopted and embraced.
